Abstract

This research was conducted in Mentimun Street, Siumbut Baru Village, Kisaran Timur Subdistrict, Asahan Regency, North Sumatera Province. Study time from March to May 2017. This research was arranged based on Factorial Randomized Block Design with 2 treatment factors and 3 replications. The first factor is PGR with 4 levels: Z0 = without PGR, Z1 = Rootone F (2 g / l water), Z2 = Atonik (2 ml / l water) and Z3 = Hantu (2 ml / l water). The second factor is by giving the ratio of manure with 4 levels ie K0 = 1: 0 (1 part of soil + 0 parts of manure), K1 = 1: 1 (1 part of soil + 1 part manure), K2 = 2: 1 (2 part of soil + 1 part manure) and K3 = 3: 1 (3 parts of soil + 1 part manure). The results showed that the best treatment of PGR was obtained at PGR Rootone F which resulted in plant height 26,36 cm, leaf number 13,71 strand, stem diameter 5,29 mm, total live crop 3,75 crop. The treatment of manure on planting medium with aratio of 2: 1 (soil: manure) is the best treatment that produce plant height 25.09 cm, the number of leaves 13.54 pieces, stem diameter 5.25 mm, the number of plants live 3.67 plants. Interaction between PGR and manure had no significant effect on all observed variables.

Abstract

Computational thinking skills are one of the important competencies in the world of education in the 21st century, especially in the fields of science, technology, engineering, and mathematics (STEM). GNU Octave as an open source software similar to MATLAB offers a numeric programming environment that can be used to train and develop students' computational thinking skills. Researchers use a literature study method that aims to see the extent to which GNU Octave can be used in learning to improve students' computational thinking skills. The literature sources used come from national and international journal articles, conference proceedings, and other trusted sources over the past 10 years. The results of the review show that GNU Octave is effective as a learning tool for numeric programming, problem solving, and mathematical modeling, and has a positive contribution to honing students' algorithmic and analytical thinking skills.

Abstract

Distribusi beras di Indonesia menghadapi tantangan besar akibat kondisi geografis yang luas dan beragam. Efisiensi dalam penyaluran komoditas ini sangat dipengaruhi oleh pemilihan metode distribusi yang tepat, terutama dalam menekan biaya transportasi. Penelitian ini membahas penerapan metode Vogel’s Approximation Method (VAM) dalam menyelesaikan masalah transportasi beras dengan pendekatan Kajian Sistematis Literatur (Systematic Literature Review/SLR). Kajian dilakukan terhadap sejumlah publikasi dalam lima tahun terakhir yang membahas penggunaan VAM dalam konteks distribusi logistik. Selain itu, disertakan simulasi kasus distribusi beras dari beberapa gudang ke sejumlah wilayah tujuan yang permintaannya diketahui. Hasil kajian menunjukkan bahwa metode VAM mampu menghasilkan pola distribusi yang efisien dengan biaya total yang lebih rendah dibandingkan metode konvensional lainnya. Metode ini juga dapat diterapkan dalam berbagai kondisi distribusi, baik pada skala lokal maupun nasional. Dengan demikian, VAM dapat menjadi alternatif solusi dalam perencanaan distribusi beras yang hemat biaya dan terstruktur secara matematis.
